Description

Since Virtual Box is passing the work to the real graphics driver (where the S3 patented algorithms implementations live), it seems that it could reveal that it has this capability and make it accessible when the underlying driver supports it.

Maybe that is true under some configurations (but that doesn't appear to be the case with my Windows Host and Linux Guest) As you can see in my Virtual Box log output, OpenGL version is 2.1.8494 (which is greater than 2.0) contains GL_EXT_texture_compression_s3tc, but a glxinfo shown further down has no such entry.
